Which statement best describes the motion of
the dye molecules in the water?
The dye molecules
o move in a directed way from high to low
concentration.
o move randomly through collisions in no
particular direction.
stay close to other dye molecules as they
move through the water.
Low
Check ansive
Answer:The statement that best describes the motion of dye molecule in water is directed from a region of high to low concentration. The motion of the particles of the dye in water is described as diffusion: diffusion is the movement of molecules of a substance from one position to another.
Explanation:
Option A is correct. The statement that best describes the motion of the dye molecules in the water is "the dye molecules move in a directed way from high to low".
The motion of dye molecules in water is known to be random. Another name for random motion is Brownian motion and since diffusion is also Brownian motion, hence we can term the motion of the dye molecules in the water as "diffusion".
The water is held together by intermolecular forces and these forces are the ones that attract the molecules of the die carrying them away and making the process of molecular transport of the dye to be accelerated (moving from a region of high concentration to low concentration).
In conclusion, the statement best describes the motion of the dye molecules in the water is "the dye molecules move in a directed way from high to low".

Explanation:
John rode 3150 m at an average speed of 350 m/min.If he had ridden at average of 375 m/min instead. How much sooner would it have taken? (In seconds)
Answer:
36
Explanation:
It would have taken 36 s for John to cover the distance.
Average speed is defined as the total distance travelled divided by the total time taken.
Average speed = Total distance / total timeTo obtain the answer to the question, we'll begin by calculating the time taken to cover the distance (3150 m) in each case.
Case 1:Average speed = 350 m/min
Total Distance = 3150 m
Time 1 =?Average speed = Total distance / total time
350 = 3150 / Time 1
Cross multiply
350 × Time 1 = 3150
Divide both side by 350
Time 1 = 3150 / 350
Time 1 = 9 mins
Multiply by 60 to express in seconds
Time 1 = 9 × 60
Time 1 = 540 sCase 2:Average speed = 375 m/min
Total Distance = 3150 m
Time 2 =?Average speed = Total distance / total time
375 = 3150 / Time 2
Cross multiply
375 × Time 2 = 3150
Divide both side by 375
Time 2 = 3150 / 375
Time 2 = 8.4 mins
Multiply by 60 to express in seconds
Time 2 = 8.4 × 60
Time 2 = 504 sFinally, we shall determine how much sooner it would have taken John to travel at 375 m/min. This can be obtained as follow:
Time 1 = 540 s
Time 2 = 504 s
Difference in Time =?Difference = Time 1 – Time 2
Difference in time = 540 – 504
Difference in time = 36 sTherefore, it would have taken John 36 s if he had travelled at an average speed of 375 m/min.

Explanation:
HOPE ITS HELP
The metal reacts spontaneously with aqueous solution of NiCl₂ is Zinc as it is more reactive.
What is reactivity series?Electro chemical series is a reactivity series which tells about the reactivity of the metals present in any solution in the increasing order.
According to the reactivity series, Zinc is present at the upper position as compares to other three given metals and their reactivity will be represented as:
Zn > Ni > Sn > Cu > Au
So, zinc will replace the nickel atom from NiCl₂ solution.
Hence option (D) is correct.

ugh help i have to write a 1 -page essay for my honors sci class
and i have no clue how to its over Photosynthesis but we have to have answer to these questions in it to :(What is photosynthesis? What role does the Sun play in the interaction of energy during photosynthesis? What forms of energy conversion occur? What form does the chemical energy take? What gas do plants release as a result?): so i have no clue how to write it .?.?.?.?.?.?
.
Answer:
1 . Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities.
2. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls.
3.Photosynthesis in plants converts solar energy into chemical energy using electrons and protons from water. The process of photosynthesis in plants involves a series of steps and reactions that use solar energy, water, and carbon dioxide to produce organic compounds and oxygen.
4 . Chemical energy is stored in the bonds that connect atoms with other atoms and molecules with other molecules. Because chemical energy is stored, it is a form of potential energy. When a chemical reaction takes place, the stored chemical energy is released.

Why does the border between light and dark on the Moon change location?

What is solar system?Solar system is defined as the Sun's orbiting objects are confined by gravity to one system. The Solar System is the only system in which a habitable planet has been observed, the only star we can observe up close, and the only planets we can explore with spacecraft. Understanding the creation and evolution of planets as well as the conditions required for life requires extensive investigation into the solar system.
The terminator is the line on the moon that divides day from night. The moon's surface is in a twilight state along the terminator line, which is where the twilight zone is frequently referred to as. The sun is either rising or setting on the moon along this line.
Thus, we only view a portion of the lighted part of the Moon because of how the Moon rotates around the Earth.
